The steam pipes may be made up of a plurality of lengths,

The casing may preferably be ar- 1-5 thereby prevent heat losses and eliminate ranged in a trendh 27 of appropriate depth.

trough, means Within the trough for supportmg a. pipe, an arched cover having depending side edge portions, the edge portions at each side of said bottom section having flanges and upstanding portions spaced from each other to form grooves receiving said depending edge portions to provide interfitting oints and cementitious material in the joints between said bottom section and cover.

3. In a steam pipe casing, a trough shaped base having extending side edges, stirrups detachably suspended frbm the upstanding side edges of the base, bearings on said stirrups, rollers having journals seating in said bearings, and a cover for said base.

4:. In a steam pipe casing, a base formed of sheet metal to provide a central trough and side grooves, stirrups suspended from the edges of the trough and comprising bearings, rollers having journals supported in bearings of opposite stirrups, and an arched cover having edge portions seated in said grooves. v
